T0 to whom, it may concern.-

Be it known that I, LEWIS W. FAIR, a citizen of the UnitedStates,residing at VValdron, in the county of Scott and State ofArkansas, have invented a new and useful Harrow, of which the followingis a specification.

This invention has relation to harrows and it consists in the novelconstruction and arrangement of its parts, as hereinafter shown anddescribed.

The object of the invention is to provide a harrow having pivoted wingswhich carry the teeth. The outer ends of links are pivoted to the saidwings. The inner ends of said links are pivotally attached to avertically-extending pin. Said pinpasses through an elongated slotprovided in the rear end of the harrowbeam. A plate is pivotallyattached to the rear end of said beam and is provided in one side -witha series of teeth. The spaces between the teeth are adapted to receivesaid pin, and thus the position of the said pin is ed along thelongitudinal axis of the said beam. A means is provided u on the beamfor retaining the forward end 0 said plate.

In the accompanying drawings, Figure 1 is a top plan view of the harrow.Fig. 2 is a cross-section of the same. Fig. 3 is a lon itudinal sectionof the rear portion of t 1e beam.

The beam 1 is provided at its forward end with the usual clevis 2 andnear its rear end with the elongated slot 3, which is located in thecentral longitudinal axis of the said beam. The wings 4 4 are providedat their forward ends with the hinged members 5, which in turn areattached to the hinged members 6, fixed to the sides of the said beam 1.The said wings 4 are provided with the usual spike harrow-teeth 7. Thelinks 8 8 are pivotally attached at their outer ends to the upper edgesof the wings 4, and the links 9 9 are pivotally attached at their outerends to the lower edge of the said wings 4. The pin 10 extendsvertically through the slot 3, and the inner ends of the links 8 and 9are pivotally attached to the said pin, the inner ends of the wings 8being located on top of the beam 1 and the inner ends of the links 9being located below the said beam 1.

The collar 11 is located upon the upper ppgrtion of the pin 10. Thebraces 12 are ed at their outer ends to the links 8 and extend up andare pivoted at their inner ends to the upper end of the pin 10, thecollar 11 bemg interposed between the inner ends of the braces 12 andthe links 8.

The plate 13 is pivotally attached at the point 14 to the rear end ofthe beam 1. Said plate is provided in one edge with a series of teeth15,the spaces between which are adapted to receive the pin 10, and thusthe said pin is positioned along the central longitudinal axis of thebeam 1. The forward portion of the plate 13 is provided with theenlarged recess 16, which is adapted to receive the said pin 10 when thewings 4 are swung in close to the sides of the beam 1. The catch 17 isattached to the beam 1 and is provided with the laterally-extending heador portion 18. The forward end of the plate 13 is notched, as at 19, andthe side of the said notch 19 is adapted to slip under the head 18 ofthe catch 17. Thus the said plate 13 is held against rotation. In orderto adjust the position of the pin 10 in the slot 3, the notched end ofthe plate 13 is swung away from the catch 17 until the edge of the notch19 clears the end of the head 18, when the free end of the said plate islifted above the end of the catch 17 and the said end of the said plateis swung to one side until the ends of the teeth 15 are beyond the sideof the slot 3. The said pin 10 may then be moved longitudinally of thesaid slot and through the links 8 and 9 and braces 10. The said wingswill be swung away from each other or toward each other, according tothe direction in which the pin 10 is moved in the slot 3. i/Vhen thesaid wings 4 4 are properly positioned with relation to each other, thesaid plate 13 is swung back into its original position in engagementwith the catch 17, when the pin 10 will be received in one of the spacesbetween the teeth 15 and securely held.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is

1. A harrow comprising a beam, wings hinged to the beam, said beamhaving an elongated slot, a pin located in said slot, links pivotallyattached to the pin and to the wings, and means for retaining said pinin fixed po sition longitudinally of the slot.

2. A h'arrow comprising a beam, wings hinged to the beam, said beamhaving an elongated slot, a pin located in said slot, links connectingsaid pinwith the wings, a plate pivoted to the beam and having teeth, acatch attached to the beam and adapted to retain the free end of saidplate the spaces between the teeth being adapted to receive said pin.

3. A harrow comprising a beam, Wings hinged to the said beam, said beamhaving an elongated'slot, a pin located in said slot, links pivotallyconnecting said pin with the Wings, a plate pivoted to the beam andhaving at one edge a series of teeth and near its forward end anelongated recess, the space between the teeth adapted to receive saidin, v and means attached to the beam for retaining the free end of saidplate.

4. A harrow comprising a beam, Wings hinged thereto, a in adapted tomove longitudinally of said beam, means for retaining said'pin in fixedposition relative to the beam, links pivotally connecting said pin wlththe Wings, braces attached at their ends to said links and pivotallyconnected at their inner LEWIS W.
